Lithiated (alpha-chloroalkyl)heterocycles, generated by deprotonation with LDA at -78 degreesC in THF, add to various enantiopure imines affording 'one pot' chiral heterosubstituted aziridines in a diastereoselective manner. Lithiated heterosubstituted aziridines, obtained by deprotonation of the corresponding aziridines with n-BuLi at -78 degreesC in THF, were trapped by electrophiles (D2O or CH3I) with high stereoselectivity.
